Trupower Cold Air Intake System 5.7L

The Stillen Trupower by STILLEN Cold Air Intake (TP403200) is engineered to be the only true cold air intake available for the 2014-2021 Toyota Tundra equipped with the 5.7L engine. After 18 months of development, STILLEN has created a system that not only increases airflow into the engine but also dramatically reduces intake air temperatures. The system incorporates a replacement radiator shroud and intake duct, channeling cold air from the vehicle's front through the core support and into a substantial airbox. This design utilizes the factory air intake opening while introducing nearly 50% more airflow via a dedicated cold air intake port. During rigorous testing, the STILLEN product development team observed intake air temperature reductions three times faster than the factory air intake. In contrast, competitor intakes tested showed higher temperatures than the stock system and failed to reach ambient temperatures. This cold air intake is designed to provide a performance boost, with claims of up to +20 horsepower and +20 torque increase. The installation is straightforward, requiring no cutting or modifications. This specific configuration, TP403200, includes a removable block-off plate and a free-flow tube system, offering extra peace of mind for customers in extreme conditions. The block-off plate can be installed in under five minutes. The oiled air filter is serviceable and backed by a limited lifetime warranty. This product is proudly made in the USA. Please note that this intake system is not for sale in California.
